This expressway is a vertical expressway line along the eastern coast of Jiangsu and is also called Jiangsu Coast Expressway. The last city that the expressway passes, Kunshan, is under Suzhou's jurisdiction.

Like Jianghu Expressway, the line crosses three horizontal expressways (Xuzhou-Lianyungang, Nanjing-Nantong and Ninghu) and strengths the expressway network for the province.
